An airway device (10) is provided for sealing a patient's pharynx (P), the device comprising an elongate flexible chamber (12) of resilient material with a leading end (14) and a trailing end (16) and being bounded by top (18) and bottom (19) elongate surfaces. The top surface has raised ridge (20) across it to seal at the base (B) of the tongue (T) and the bottom surface is shaped to seal at the back of the patient's throat. An opening (26) is defined in the top surface and serves to place the chamber in communication with the laryngeal inlet (L) of the patient. A gutter (28) extends from the leading edge along the length of the bottom surface and forms a funnel (27) at the trailing end. Instruments passed along the outside of the stem are received in the funnel and directed along the gutter to the oesophagus (O) of the patient. A hollow stem (40) protrudes from the trailing end of the chamber for passing through the patient's mouth and has an attachment formation (42) with a 22 mm diameter, for attaching to external ventilation apparatus. |
